Re: [cobalt-users] Raq4r Email Server Timing Out..??

[Jerry Farquhar <jerry@xxxxxxxxxxx>]

Well it seems like the email client Outlook is making the connection to 
the server since it identifies the server and is able to indicate how 
many messages are on it for download..

What happens next is that Outlook either just hangs waiting and waiting 
and now messages are downloaded or it may download a few messages then 
stop with a time out message.

It gives the impression of network or Internet congestion yet access to 
the web sites on the server are pretty quick and watching the mail spool 
across the server the server never has been seen timing out or 
indicating any errors on it's side.

Do you think that some kind of intermitten DNS related issue could be 
causing this??  

I will try your suggestion.. and use IP inseatd of name to see if that 
resolves the problem.

Thanks much for your input!!

Jerry
